I was hoping - eventually - to provide enough variety to give vitamins, minerals etc and be able to stop giving pellets (I'm thinking root veg for calories/bulk). So, grass as a basis, legumes inc clover for protein, grassland herbs for...herby stuff! Chicory is fantatic for growing lambs, I might try and find room for that somewhere.
It also has to survive British "summer", look close enough to an ornamental lawn for nosey landlords, and it would be nice if the same batch of seeds could do the south facing lawn AND the north facing scrappy land. And I'd probably chuck some in the fodder growing system too, for winter.
Hmmm...
Edit - I also didn't know about endophytes until the other post on this board - how big an issue is this? IT's not something I've come across relating to any normal livestock (but it was mentioned in context of horses which I know can be more delicate).
